Praat is a computer program for analysing, synthesizing and manipulating speech and other sounds, and for creating publication-quality graphics. It is open source, and available free of charge for all major computer platforms (MacOS, Windows, Linux), on both 32-bit and 64-bit operating systems. It can be downloaded from A speech corpus typically consists of a set of sound files, each of which is paired with an annotation file, and metadata information. Praat’s strengths are in the acoustic analysis of the individual sounds, in the annotation of these sounds, and in browsing multiple sound and annotation files across the corpus. Corpuswide acoustic analyses, leading to tables ready for statistical analysis, can be performed by scripting, as described by Caren Brinckmann elsewhere in this book
